Caterpillar CAT Marine Power Air Inlet Manifold / Aftercooler Housing - Used

Caterpillar CAT Marine Power cast aluminum air inlet manifold with integral aftercooler housing and finned charge-air core, removed from an inline 6-cylinder CAT marine engine. **Application:** Inline-6 Caterpillar marine engine — appearance is consistent with the 3126B / 3126E / C7 marine family, but the application is NOT verified. The numbers found on this housing (`11061` and a partially legible `237-3980`) are foundry/casting marks, not confirmed orderable Caterpillar service part numbers. **Condition:** Used, untested take-off. Chalky white oxidation and surface dirt typical of aged marine aluminum, light rust staining at the steel studs, minor casting scuffs. Aftercooler core fins appear present in the photos. The housing and core have NOT been cleaned, pressure tested, or flow tested and machined surfaces have not been inspected. Plan on cleaning, inspection, and pressure testing before installation. Coolant and air passages will be drained and ports capped before shipment. Gaskets and hardware not included. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
